我刚刚发现我的登录和注册表单中,isset函数不再起作用了。很奇怪,我认为,所以我撤消了最近做过的所有操作,看看是否是这个问题导致的,但没有成功。如果我删除isset并替换为以下代码,则可以正常工作;
if($_SERVER['REQUEST_METHOD'] == "POST"){
它可以工作!但是我在一个页面上有两个表单,因此我需要检查哪个被提交了。
下面是isset函数:
if (isset($_POST['submit_login'])) {
提交按钮的名称是正确的,您需要知道这一点。
<input type="submit" name="submit_login" value="Login" class="buttonClassic"/>
注册表单的提交按钮和登录表单的一样,只是名字不同,名字为submit_reg
。
表单:
<form action="<?php echo htmlentities('Login'); ?>" method="post" id="login">
<p class="p1">Already signed up? Log in</p><hr/>
<label for="email">Your email address </label><input type="email" required name="email" placeholder="Email" class="text" id="email">
<label for="password">Your password </label><input type="password" name="pass" required placeholder="Password" class="text" id="password">
<center><input type="submit" name="submit_login" value="Login" class="buttonClassic"/></center>
<div class="center-align-text">
<p class="p3"><a href="passreset.html">Forgotten your password?</a></p>
</div>
</form>
注册表单:
<form action="<?php echo htmlentities('Login'); ?>" method="post" id="register" >
<p class="p1">New to NBS? Sign up, it's free!</p><hr/>
<label for="reg_email">What's your email address? </label><input type="email" name="email" required placeholder="Email" class="text" id="reg_email">
<label for="reg_password">Choose a password </label><input type="password" required name="pass" placeholder="Password" class="text" id="reg_password">
<label for="reg_password2">Re-type password </label><input type="password" required name="pass2" placeholder="Re-type password" class="text" id="reg_password2">
<input type="checkbox" name="subscribed" value="subscribed" id="subscribed"><label for="subscribed">Yes, send me email updates from NewBorn Sounds. </label>
<br/>
<input type="checkbox" required="flag" name="terms" value="ticked" id="terms"><label for="terms">I agree to the <a href="Terms">terms & conditions</a>.</label>
<center><input type="submit" name="submit_reg" value="Sign Up" class="buttonClassic"></center>
</form>
如果您需要更多帮助,请大声喊出来!
哦,我知道我可以将表单提交到外部PHP脚本,但我不想这样做,因为我希望用户输入错误能够输出到同一页。我知道我可以使用ajax,我也确实这样做了,但我正在尝试将javascript作为附加组件,并且不希望为了没有js而降低用户体验。
完整的HTML:
